WHAT IS APRS ... Automatic Packet Reporting System ... NOT just Position
Here is one explanation that shows it is more than just your Lon Lat (position) when using a Kenwood D700/D710/D7
|
The tracker
alone does
not allow
you to
observe at
all. It is a
transmit
only device.
The
D700/D710/D7
are
bi-directional
devices that
allow you to
not only
transmit
APRS
position
reports, but
to also
observe and
interact
with others
around you.
You can also
receive
other types
of
information
passed via
the APRS
network that
include but
are not
limited to:
locations of fixed assets such as: repeaters (including freq and PL) digipeaters people's houses hamfest locations eyeball QSO gatherings traffic jams locations of moving assets such as: people driving (possibly who you are planning on meeting up with) airplanes trains boats balloons hikers objects of various descriptions: satellite passes weather events communication with others: via text messaging on APRS via email on APRS via voice alerts via status messages including voice frequencies and much more. None of this is observable on a tracker. Full blown APRS clients running on laptops allow you do just about everything available in APRS, the Kenwood units give you the ability to do most of the above all in one small neat package.
